【Abstract】 This paper describes a CNC system for cam shaft grinding machine. The system uses numerically controlled contouring with rocking table,adopts forced coupling between workpiece running and rocking table swing, and improves the control precision of workpiece contour through digital regulation techniques. The paper introduces the technique characteristics of the system and the design of the digital regulators.By reforming a cam shaft grinding machine model M8312 into a CNC grinding machine, the practice shows that the CNC system is of cost effective.更多还原
